I have a set of radials I just put on my car. A 1955 Victoria. Does anyone know what the correct tire pressure is. Thank You.

I start with the maximum cold inflation pressure stated on the side of the tire and try it for awhile. You can always adjust the pressure for best performance. I inflate mine to 10% over the max cold spec. It doesn't hurt the tires and handling is more responsive. Also helps gas mileage due to reduced rolling resistance. I would not go over 10%.

The only car I have radials on is my 63 Galaxie XL convertible, I have kept the at 30lbs cold for the last 7 years with no problems.

The tire will tell you when it is correct. Assuming there are no other suspension, steering or alignment issues - Wear in the middle means too much pressure. Wear on the edges means too little pressure.

Tire size would help in giving a correct answer. My whitewall radials on my '55 Thunderbird call for 35 psi, and it steers much easier with that than 30 or 32. Check the sidewall for best answer, it will be printed there. Joe-JDC

Different tires will require different recommended pressures. In your case, tire sizing will make a difference. The recommended pressures on the side of the tire are always a good place to start but if the tires are not originally designed for the weight of the vehicle they are being placed on, then expect to adjust those values.
The 205/65RX15 tires on my ’55 simply call for 51 psi maximum. I obviously don’t air them up to that and instead run them at 35-36 psi for normal driving. For the road race, I increased the air pressure up to 42 psi but lowered it back down once the race was over. If the tires are larger or smaller than the original equipment tires, then the tire pressure must be adjusted accordingly.
